H. COOK REFLECTIVE SIGN April 24, 1951 Filed Feb. 28, 1945 INVENTOR H.420 o Coax W mac/V Patented Apr. 24, 1951 UNITED STATES PATENT OFFICE REFLECTIVE SIGN Harold Cook, Milwaukee, Wis.

Application February 28, 1945, Serial No. 580,244

1 Claim.

This invention relates to improvements in display materials and more particularly to a display material for signs, plaques, backgrounds, fixtures and the like.

An object of the invention is to provide a material having multiple directional reflection means not found in similar display material now in use.

Another object of the invention is to provide an improved method of constructing display material of the type which will enhance its reflective value.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing in which:

Fig. 1 is a plan view in elevation of a sign letter constructed of display material embodying my invention.

Fig. 2 is a plan view in elevation of an ornamental panel of similar display material in modified design.

Fig. 3 is a fragmentary view in perspective illustrating a step in the constructive process.

Fig. 4 is a sectional view of a panel showing the irregular placement of the reflective units.

Referring more particularly to the drawings, the numeral I0 refers to the device generally, having a base portion I I with a marginal rim I2 cast or otherwise formed in one piece, preferably of suitable plastic material. A secondary plastic [3 is poured or troweled onto the base II within the confines of the marginal rim I2. The rim I2 may be dispensed with if desired.

The secondary plastic material I3 is compounded to harden in permanent form, but when applied to the base I I it is still soft or tacky and has an adhesive quality. Units of reflective material or small mirror elements are then spaced about the surface of the plastic I3. Before the said plastic hardens the units of reflective material or mirror elements I4 are depressed with an instrument I5 or with the finger in such manner that they set in a multiplicity of planes when the plastic I3 has hardened. The operation of applying pressure to embed the reflective units or mirror elements also serves to cause the plastic adhesive to cover, bind or point the edges of the same, and this is especially desirable when mirrors are used.

It will readily be understood that setting the 2 reflective at different planes will cause a profusion of reflections of any available light.

In Fig. 1, the display material forms a sign letter, and in Fig. 2 a decorative device is shown and is formed in a like manner by the same process, and suggests the diverse design effects which can be achieved.

The base II may be formed as the first operation and a raised rim I2 may then be applied, or the base and rim may be cast or otherwise formed as a unit.

Fig. 3 illustrates a method of changing the pitch of each element I4 by pressure of the instrument I5, and Fig. 4 shows the diverse planes resulting when the secondary plastic I3 has hardened.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

A display sign comprising a flat base of plastic nonreflective material, a plurality of relatively spaced reflective elements embedded in the upper surface of said base and disposed thereon in asymetrical variegated planes whereby a substantial portion of the non-reflective surface is exposed, and substantially planar reflecting surfaces on said elements.

HAROLD COOK.
